connection-string

问题 Is there an existing method in C# to extract the file path from a string that represents a ConnectionString to a SqlCE .sdf file?

问题 This is about ConnectionStrings / ASP.NET MVC with Visual Studio 2012 ultimate & SQL Server Express 2012. Following up with this tutorial here: http://www.asp.net/mvc/tutorials/mvc-4/getting-started-with-aspnet-mvc4/intro-to-aspnet-mvc-4 I came across an issue with these two connection strings at my web.config: <connectionStrings> <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\v11.0; Initial Catalog=aspnet-MvcMovie-users; Integrated Security=SSPI; AttachDBFilename=

问题 Wanting to deploy my project on different servers I would prefer to be able to specify a connect string using a relative path. I can't seem to get that to work and want to know if there is some trick to it...? 回答1: A suggestion You could build the absolute path in the app and pass that in the connection string. So, if you know that the database file is in the database subfolder of the application folder, you could do something like this (C#): string relativePath = @"database\myfile.s3db";

问题 I want to read just a connection string from a configuration file and for this add a file with the name "appsettings.json" to my project and add this content on it: { "ConnectionStrings": { "DefaultConnection": "Server=(localdb)\\mssqllocaldb;Database=aspnet- WebApplica71d622;Trusted_Connection=True;MultipleActiveResultSets=true" }, "Logging": { "IncludeScopes": false, "LogLevel": { "Default": "Debug", "System": "Information", "Microsoft": "Information" } } } On ASP.NET I used this: var temp

问题 I am trying the following solution and not having much luck: How can i update app.config connectionstring Datasource value in C#? The code I have is: Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None); // Because it's an EF connection string it's not a normal connection string // so we pull it into the EntityConnectionStringBuilder instead EntityConnectionStringBuilder efb = new EntityConnectionStringBuilder( config.ConnectionStrings

问题 I have two websites running on the same Windows 2008r2 64bit server, SQL Server Web edition. Both sites are identical with just the connection string pulling the data from a different database. Both sites are running in different application pools - both .net 2, classic pipeline, 32bit - and the website is quite old being developed back in 2005. Most of the data access is in compiled dll's in the bin directory. If I print out the connection string I'm using by calling ConfigurationManager
